Sailing trip

I would be glad if someone could correct my letter.

Hi Alex,

I´m so pleased to hear from you. Indeed, I´m coming to Portugal in July, I couldn´t turn down the invitation. I took up sailing as a hobby when I was a child and everysummer as long as I can, I go. However, I couldn´t go last summer, I was doing my internship in India and the flight was really expensive, so I couldn´t afford to come back home just for sailing.

During my trip, I would rather go to the beach and chill out than enter a boat race. I would prefer to enjoy the sun and relax on the sand, just listening to the seagulls and the waves crashing into the rocks.

Lina told me that if there was enough space on the ship she would like to join us. She is also keen on saling since she was a child.

Best wishes,

Lucia

Dearest Alex, 

It's good to to hear from you. I couldn´t turn down the invitation, so I'm coming to Portugal in July.  I started sailing when I was little and try to go sailing every summer, but while in Portugal, I'd rather go to the beach and chill out than deal with a boat race. I just want to enjoy the sun and relax on the sand, just listening the seagulls and the waves. Lina told me that if there was enough space on the boat she would go with us.
Warm regards,
Lucia

Hi Alex,

I´m so pleased to hear from you. Indeed, I'm coming to Portugal in July, afterall I just couldn´t turn down such an invitation. I took up sailing as a hobby when I was a child and since then, I've been doing it every summer for as often as possible as long as I can, I go. However, I couldn´t go last summer, as I was doing my intership in India and I could ill afford the expensive flight back home just for sailing the flight  was really expensive, so I couldn´t afford to come bach hoe just for sailing.

During my trip, I would rather go to the beach and chill out than enter a boat race. I would prefer to enjoy the sun and relax on the sand, just listening to the seagulls and the waves crashing into de the rocks.

Lina told me that if there was enough space on the ship, she would like to take part with join us. She is has also always been keen on sailing since she was a child.

Best wishes,

More or less you actually successfully did get your message across. It would have more than sufficed as a letter. However, instead of just making slight corrections to your letter, i took the liberty to rephrase some sentences, to make it more fluent for your reader. I think that you could surely improve on being fluent with more practice :)
